the dichotomy of the branchlets, is 9 lines long, and is divided at its summit into 
2 branches, each bearing few flowers; pedicels 2 lines long; sepals ovate oblong, sub- 
membranaceous, 13 line long, with several minute scales inside; tube of corolla nar- 
rowly cylindrical, 6 lines long; segments linear-oblong, 5 lines long, simply and sinis-

A small lactescent shrub 6 feet high, with dichotomous slender branchlets; leaves | 
lanceolate-oblong, cuneated at the base, acuminate, submembranaceous, pale green 
above, opake, entire, glabrous, nerves very patent (as in T. neriifolia) and immersed, 
below yellowish, opake, with immersed dark pellucid nerves, with no apparent veins, 
2-5 in. long, 9-18 lines broad, on slender petioles 3-6 lines long; racemes in the dicho- 
tomies of the branchlets, much shorter than the leaves; peduncle very slender, 1 in. long, 
bearing 4-5 flowers on alternate pedicels bracteolated at the base, 5 lines long; sepals 
1 line long, acute; tube of corolla salver-shaped, 5 lines long, a little broader below the

convoluted; stamens somewhat exserted in the mouth; 2 free oblong, pointed ovaries, 
surrounded at their base by a disk } their length; follicles obovate, oblong, green,

transverse line; panicle between the terminal leaves, 2 in. long, 14 in. broad, with many 
rather close, somewhat stoutish branches again and again divided; numerous flowers - 
on pedicels 2-4 lines long; sepals small, ovate, imbricated, ¿ line long, each furnished ;
